The :takeeup roll l2 has secured to the ends thereof gudge'ons I4 journalled in suitable bear ingsucntheinside frame webs ill. The gudgeons M on the left-hand loomside has secured; thereto between the two frame'webs l0 and .H a gear: lfiiby which the take-up roll i2 is continuously driven as thecloth is formed. The take-up .roll gearrlfi is driven from .the crankshaft. of the loomtinoltshown), which extends parallel to the axis of the take-up roll l2, and-which drives through a pair of intermeshing gears (not shown a short pick .cam shaft (not shown) ,below said crankshaft on the left-hand side of the loom. On said pickcam shaft is connected az-bevel-gear; (not 7 shown) meshing with a; second' bevel v ear (not showni-on' a driveshaft 22 (Figs. Z and 4)". Between the drive shaft'ZZ and the "take-up roll gear 16 is the take-up gear transmission.

As a -feature of'the present invention, the take-- up'gear transmissionismounted in a box or cas-i ing'25 formed with a peripheral wall 26, extending through an opening 21in theouter frame web H. The gear box -25 has a mounting flange 39 abutting'the' outer face of the 'frame-web -l t around the webframe opening -2l,-and is closed at its left-hand side by-a'plate wall 28 secured to sai'd fiange 3i) and'to said frame' web H by means of screw studs 3|? The platelwall 28 is provided-with 'a'fian'ged opening .33'*-'closedby a removable cover p1ate"34 supported" in posi-- tion by "means of screw studs 35.} The coverplate 34 is in readily accessible position "and-can be removed mpermit access to the interiorof' the gear'box'25, 'as for example, for the purpose of changing the speed ratio according to the d'e sired pick. "The cover plate 34 is desirably of transparent non-shattering material such as nucite or fPlexiglass, to serve as a'window', so that ti'i -ihteriorfof the gear box tican be easily'ob The gearbox 25 isprovidedwith a partition wall 31 serving as a frame support fol-"certain of 'thelbelarings of'the shafts of the take-uptrans mission train, and has an outerfwall 38 units rightehand side, serving asa support for the bearings'of someof'the'shafts of thegear train;

. nthe right-hand side of the gear box 25 an ex ension 40 passing'throughan openi il f ner remsw andha insiam tension a worm 45 meshing with a worm wheel 46 mounted on a take-up main drive shaft 41. The take-up main drive shaft 41 has one section journalled in bearings 48 in the box walls 31 and 38 respectively, and has a sectionof reduced diameter journalled in bearings 5| in the left-hand box wall 28 and passing through said latter wall to the outside of the gear box 25.

The outer end of the reduced shaft section carries a hand wheel 52 for manually taking up or reversing the rotation of the take-up drive.

As a feature of the present invention, the

4 the end of said reduced section. When the hub extension 81 extends to the right of the gear 69 as shown in Fig. 2, this pick change gear will be in mesh with the idler 66. The gear 69 is re- I movably retained on the second countershaft I0 by means of a screw stud 90, and can be reversed in position on said second countershaft when it 7 is desired to operate in the upper pick range.

take-up gear transmission between the take-up main drive shaft 41 andthe take-up roll gear I6 issuch as to permit quick and easy changes in speed ratios, in accordance with the picks per inch desired. To that end, the take-up gear transmission comprises a pinion 60 afiixed to the take-up main drive shaft 41 between the two gear box plate walls 31 and 38, and meshing with a gear H on a first countershaft 62 journalled in spaced bearings 63 and 64 in said walls 31 and 38 respectively. Affixed to the overhanging section of the countershaft 62 is a first drive gear 65, which meshes with a first change gear idler 66 secured to an idler shaft 61 journalled in bearings in an idler gear adjusting bracket 60, and which is employed when operating in the lower-"pick range. The idler gear 66 meshes with a take-up driven change gear 69 on a second 'countershaft I0 supported in bearings H and I2 in the walls 31 and 38 respectively.

The bracket 68 is mounted for rotative idler gear adjusting movement about the axis of the countershaft :62, and comprises a pair ofspaced plates 'I5land I6 journalled on said countershaft 62, and rigidly'held together by means of bolts 11 passing through respective spacer sleeves 19 between said plates. The bracket plates 15 and I6 carry respective bearings for the idler shaft 61 and respective hubs'embracing the countershaft 62. Between the two bracket plates 15 and I6 is the first countershaft drive gear 65, and alongside of said gear is a second drive pinion 80 aflixed to the countershaft 62. The drive pinion 80 is half the-diametricalsize of the first drive gear 65, and is employed when operating in the upper pick range. Meshing with the second drive pinion 80 is a second change gear idler 8Isecured to a second idler shaft journalled in hearings in the bracket plates 15 and 16 respectively, and adapted 'to mesh with the take-up driven change gear 69 on the second countershaft I0, when said change gear is in position on said second countershaft reversed from that shown in Fig. 2 for operation in the upper pick range. v I

The bracket-68 may be rotated in adjusting position about the first countershaft 62, to bring either of the two idler gears 66 or 8| in mesh with the selected change gear on the second countershaft 10 according to the pickrange desired, and is secured in adjusted position by means of a clamp secured to a boss on the gear box plate wall 31.

The driven gear 69 is mountedon a reduced section of the second countershaft I0, and in the lower pick range of operation, shown-in Fig. 2, said pick change gear has an axial hub extension 81 abutting a shoulder on said countershaft at Also afiixed to the second countershaft 10 is a drive gear 92 mounted between the two walls 31 and 38, and meshing with a driven gear 93 on a third countershaft 94. The countershaft 94 is supported in bearings 95 and 96 in the walls 31 and 38 respectively, and extends to the outside of the gear box 25. On the projecting part of the countershaft 94 is afiixed a drive gear 91 meshing. with an idler gear 98 which is in mesh with the take-up roll gear I6, and is secured to an idler shaft 99 journalled in a bracket I00. The bracket I00 is supported for rotatable adjustment about the third countershaftto maintain the idler gear 98 in mesh with the take-up roll gear I6.

As a feature of the present invention, means are provided for positively lubricating the gear transmission in the gear box 25, and for that purpose, the drive shaft 22 carrying the take-up worm 45 drives a lubricating oil pump I05 mounted in the gear box extension 40 on the front wall thereof. The lubricating pump I05is shown of the gear type, and comprises a pair of meshing gears I06, serving as the pumping members, and one of which is fixed to the shaft 22 so as to be driven thereby. The pump I05 has an intake I01 leading from the sump section I0'Ia of the gear box 25, and, has an outlet I08 connected to a piping system I09 distributing oil to the different rotating members of the gear transmission. The oil distribution piping system I09 may be of any suitable type, and may have a manifold III] at its upper end provided with openings for projecting the oil downwardly from the top of the transmission. The oil from the manifold IIO will find its way through the different rotating parts of the transmission and back into the sump 101a.

With the construction described, the box en.

closed take-up gear transmission will be protected against lint, threads, waste and other foreign substances. Also, by means of this construction, each of the gears of the transmission is keyed'to a shaft supported in two or more spaced bearings,

so that a rigid inflexible structure free from vibration or play is afforded. Moreover, with this encased construction, lubrication of the gears and bearings is effected efiiciently without creating an untidy, oily mess around the loom. Furthermore,

determine through the transparent window 34 the pick setting of the loom from the position of the pick change gear 69 and from the number of teeth thereon, which would be marked on the gear.

The construction of the present invention is provided with means for driving the take-up mechamsm in the reverse direction to the extent,

required to effect the desired let-back whenever there is an absence of the filling, as a result, for

example, of the breakage or exhaust of the runmng filling supply. To that end, or for the pur-" pose of manually pulling the cloth ahead or back, as is necessary in the initial starting of the loom or positioning the fell of cloth, there is a clutch III in the take-up transmission automatically disengaged upon detection of a failure in the filling. The clutch I I I is of the ratchet tooth type, and comprises a clutch element II2 fixed to the take-up worm wheel 46, and meshing with a complemental clutch element II3 feathered on the take-up main drive shaft 41 for slidable movement therealong.

The clutch element H3 is yieldably urged into drive engagement with the clutch element II2 by means of a coil spring I I7 embracing the main shaft section I I4, and bearing at one end against a shoulder or collar I I8 on said shaft section, and at its other end against said clutch element H3.

The disengagement of the clutch I I I is effected automatically upon detection of a deficiency in filling by means of a filling feeler slide mechanism I I9 which may be of the usual type, and which is operated when the filling breaks, or when the filling is being replenished, to move a rod I20 on the inner side of the inside frame web I downwardly. The rod I is guided for slidable movement and urged upwardly in an inoperative position by means of a spring I2I seated on one of the slide sleeve guides I22 aifixed to the inner face of the inside frame web I0, and bearing against a collar I23 secured to said slide rod I20. The slide rod I20 carries a block I24 which engages on its lower side, one end of a cam lever I25 pivoted to the front wall of the gear box extension 40, and which is adapted to engage on its upper side in the upper limiting position of said slide rod, a sleeve rod guide 129 aflixed to the inner face of the inside frame web I0. The other end of the lever I25 has a cam conformation I21 engaging a cam follower I28 secured to a rock shaft I30 journalled in the front and rear walls of the gear box extension 40, and carrying inside said extension a fork I31 engaging the clutch element I I3, and serving to shift said member out of engagement with the clutch element II2 when the slide rod 120 is depressed, either upon filling transfer action, the breakage of the filling, or for manual operation.

The slide rod I20 is automatically operated,

from the filling slide mechanism H9, or may be manually operated by means of a foot pedal I32 integral or otherwise secured to the collar I23.

Upon the automatic or manual disengagement of the clutch II I in the manner described, the tension of the cloth A will cause a reverse drive or let-back of the transmission beyond said clutch III without interfering with the rotation of the drive shaft 22 and the intermeshing gear members and 46 thereby.

As many changes can be made in the above apparatus, and many apparently widely different embodiments of this invention can be made without departing from the scope of the claim, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

What is claimed is:

In a loom, a frame web extending along one side of said loom and having an opening, a takeup roll gear, a take-up main drive shaft, a gear transmission between said shaft and said gear, a casing for said transmission passing through said web opening from the outer side thereof, and having an outer side wall mounted on said frame web, said outer side wall having an opening afiording access to said transmission in the interior of said casing, and said casing comprising a removable cover plate for said last-mentioned opening on the outer side of said frame web.
